Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A new paper from Pankaj Mehta of Boston University of Jané Kondev of Brandeis that was recently posted to the arXiv preprint server looks at how the fundamental constants of physics might be applied to life as we know it—and even life as we don't know it yet. Their idea doesn't necessarily give the answer to the ultimate question, but it does tie two seemingly disparate fields nicely together. /news/2025-09-life-constants-physics.html Astronomy Astrobiology Wed, 24 Sep 2025 12:29:03 EDT news677935741 The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843. /news/2025-09-years-quantum-mechanics-scientist-glimpsed.html Optics & Photonics Quantum Â鶹ÒùÔºics Wed, 24 Sep 2025 12:03:03 EDT news677934181 Researchers have built on past studies and introduced new methods to explore the nature and role of subsurface fluids, including water, in the instances and behaviors of earthquakes and volcanoes.
